The Matrox VS4 Quad HD Streaming/Capture Card for Wirecast is a PCIe x8 card that allows you to simultaneously stream and capture from up to four independent SDI video sources using available Wirecast Studio and Wirecast Pro software. The capture card only works with the Wirecast software, which allows you to switch between input feeds and add effects to produce a live streaming program. The inputs support PAL, NTSC and various flavors of HD video. Each input works independently, and features auto format detection that allows the card to set the correct input format. This means that the card can accept, stream and encode for capture video from four different inputs with four different formats, even mixing SD and HD, at the same time.

The VS4 features ISO recording, which means that while streaming the program live the VS4 can also encode video from each input at up to 300 Mb/s, to available video storage. The VS4 features codecs compatible with editing solutions from Adobe, Avid and Apple, this allows you to go back and re-edit your show after it has already streamed live. Supporting 8 channels of embedded audio per input, the card encodes audio at 24-bit resolution at 48 kHz for clean clear sound. The VS4 is PC compatible, running on the Windows 7 OS.

Inputs

Four SD/HD-SDI inputs are active at all times. The VS4 auto senses the video signal and automatically sets each input up for the correct format. Each input is independent of the others, so you can feed a different format to each input with any issues.

Software

The VS4 only works with available Telestream Wirecast Studio or Wirecast Pro streaming software.

Formats and Codecs

You can mix and match video formats, stream and capture (to available storage systems) using the VS4 with the Telestream software. The VS4 Matrox supports encoding at up to 300 Mb/s from each input and supports the Matrox MPEG 2 I-Frame codec, DV, DVCPRO, DVCPRO50, and DVCPROHD codecs.
